A person (man or woman) who enjoys partaking in the act of gulping down some nice tits. This can involve a kissing, sucking, or licking motion, or a combination of the three among other creative actions.
1. Boy Joe sure went to work on my knockers, he's a great tittygulper compared to what I've experienced.
2. All I know is...with a smile like that...he's got to be one hell of a tittygulper.
